摘要
综述了有初应力的钢管混凝土柱承载力的研究现状与主要结果.介绍4种有初应力的钢管混凝土柱承载力的计算方法,分析了各自的基本特点和影响因素,并将计算结果与试验结果进行了比较.分析结果表明,4种计算方法中方法4较适合工程应用,其次是方法3和方法2,方法1相对来说偏不安全,不宜采用.
The present situation of the research and the mainly result are summarized for the capacity of concrete filled steel tube （CFST） columns with initial stress. Four methods for calculating the capacity of CFST columns with initial stress by far are concluded. Basic characteristics and factors of each method are expatiated, and calculating results by each one and testing results are compared. Results indicate that the fourth method can be more preferable used than the sencond method as well as the third method in engineering application, the first method is partly nisecurity and not suitable to be applied.
